The Arizona Department of Game and Fish detailed the cases in a monthly report released Thursday.

The agency says a female pup with the Hoodoo Pack was found dead in Arizona in March. The cause remains under investigation.

A male pup with Arizona’s Bluestem Pack died after being captured for a medical evaluation. Officials say testing confirmed the animal had canine distemper.

The most recent survey conducted by federal and state officials involved in the reintroduction program showed at least 113 wolves spread between Arizona and New Mexico. That marked an improvement over the previous year.

The survey also showed that 50 wild-born pups survived in 2016 compared with half that the previous year.
